Multiplayer

Call of Duty 4 provides a fresh new way to play multiplayer online, or at home against your friends. There are many new features to the multiplayer, including Create-A-Class, killstreaks, and new gametypes.

Online

The Online multiplayer connects you to opponents around the world to play against. Their are different modes available, and these can be found in the corresponding playlists. In addition, matches can be public or private. Public matches connect you to anyone to play against, where private matches are invitation only and often have custom rules. In either type of match, up to 16 players are supported.

Splitscreen

There is a local multiplayer feature known as splitscreen. In this multiplayer version, all the modes in online multiplayer are available to the users. However, only people on that console my play against each other, so it's usually best to have a smaller map to play in. In Splitscreen, all players are viewing their character on the same TV screen, hence the name "splitscreen". There are only preset classes in Splitscreen.

System Link

System Link is the connection of multiple consoles through a Local Area Network, or LAN. This usually involves and local network, or consoles connected through cables. System Link multiplayer is the same as splitscreen other than there being multiple consoles and screens, making this a preferred way to play for tournaments or parties. It is also possible to have up to 16 players on a single map, so larger maps are more likely to be used. Create-A-Class is not available in System Link.
